custom box help??

[WeekendPlinker]

Could someone check out this box design and tell me if im right on my math?
is the port dimension right for the sub?
will this configuration work? any other info/advice you can give me
id be happy to pay someone to help me get this right.
i don't want to waste material and labor building the wrong box

02 GMC Yukon
Pioneer 8600BS headunit
pioneer 4ch 600rms powering front componets and rear 3way's
pioneer gm-d9601 mono amp 1200watts RMS @ 1 OHM
DC LvL 3 15" Dual 2 OHM

Box:

width: 24.5"
height: 20.75"
depth: 18.5"

port width: 2.5"
port height: 18.5"
port length 1: 15.25"
port length 2: 13"
total port length: 32.75

Box volume: 3.43cu. ft after port

After sub displacement i should be around 3.25cu. and
between 31-32hz if this is right.

sub firing up, ported to the back

if this is your first sub enclosure that your building id recomend you build a sealed enclosure they dont require as much material you also get tight bass it will increase the power handling of the speakers and far less chance of blowing the speakers

If you can wait till Monday I can run it through my program at work.

However off of just math I am showing 3 cu ft. After displacement. And 32.9hz tuning. Your port length is actually 31.5.

Ive used the12volt, re box calculator, fosgate box wizard, and torres. everything i come up with after hours of mesing around with the software when i ask someone to check it out and see if its right or wrong im told its either more or less than im shooting for.

im wanting a 3.25 cu. ft box tuned between 31-32hz

no wider than 24.5" no taller than 20" and as deep as it needs to be but i dont wana give up all my cargo space.

sub firing up port firing back.

eventually another sub will be added with a cloned box and all tied together with finish trim.

should the port fire back from the driver side or since im adding another in the future should they both fire from the center?

thanks in advance

that 12volt site is awsome it was a big help when i was wiring all 4 12 inch dvc subs in series/parallel

Make the whole box 1.5" deeper and you will be good.
